I wish there was some kind of "screw off" skill where small monsters just get deflected off of you if they attack. Level 2 of the skill gives them damage when they deflect, level 3 of the skill kills them, sends them flying and can cause their launching to be used as a weapon against other monsters nearby.
What could work well would be an item called 'Pheromone', or something similar, which basically makes small monsters not attack you, maybe even make them attack the larger monsters. Like Velociprey would do to Rathian in MHFU.
I lost out on carving a KechaWacha because a pack of asshole Genprey paralysed me three times in a row. Seriously, fuck small monsters.
